Critical factors affecting labor productivity within construction project implementation: a project manager's perspective
The present study aims to identify critical factors affecting labor productivity within the construction project implementation from the project manager’s viewpoint. By a comprehensive review of the previous studies, this study identified 45 critical factors impacting construction labor productivity, which were grouped as primary 6 groups include: manpower, management, work condition, project, and external factors. A total of 56 valid samples were collected by 65 project managers' respondents who completed a structured questionnaire survey according to their previous participation in or directly implementation construction projects. These critical factors were ranked based on their relative important index and descriptive statistics (i.e. mean and standard deviation). The analysis of the identified critical factors indicated that the most significant critical factors impacting construction labor productivity are 'ability of construction management', 'financial status of stakeholders', 'work discipline', 'design changes', 'timeliness of remuneration', 'economic conditions', 'lack of supervision', 'accident', 'availability of labors', and 'availability of materials'.
